Ironbreaker Antili of the guild The Nexus on Volkmar sums up the dangers of new patches going live quite well.
“Right now, walking through WAR is like walking through Hiroshima after the bomb.”
Now, personally I haven’t had a ton of problems that make the game unplayable by any means. I don’t understand how so much could be broken and unaccounted for, but this just means overtime for the coders at Mythic. Filtering through the piles of crash related bugs, another poster brought up that MANY of these bugs were reported in-game and on the forums during the PTS events. Not good Mythic, not good at all.
Expect a post-patch hotfix VERY soon.
